Hi friends, tell me a good scheme bass EQ and preamps, I want something of innovations solder, the output stage is made, now I want to continue working on combo .. I would be grateful for your help! Sorry for English!

Search this very Forum.
There's tons of Bass Amp schematics posted: Ampeg/Gallien Krueger/Fender/Peavey/SWR/Kustom/Hartke/etc.
Just get into the Schematics thread and go backwards, also the "Music Electronics" one and "Other amps".
Once you find something you like, you can ask here (linking to the schematic) so we comment on any doubts you have.
Only problem is that you'll have to design the PCB yourself.
But there is a Treasure of info in this Forum, you'll just have to dig it.
Good luck.Juan Manuel Fahey -
Would you prefer tube or soild state?
Here is a link to a nice bass preamp: http://www.albertkreuzer.com/pics/el...eamp_sch21.gif

I really like that midrange selector. I might have to borrow that for a tube circuit."Stand back, I'm holding a calculator." - chinrest

On Loudthud's schematic shouldn't IC2a have a resistor to ground (like IC2b) for the bias current/ref voltage on its + input?Comment

I'm the worst guy in the world when it comes to opamps, but I'll try to answer this question and somebody can correct me if I'm wrong.
My impression in looking at IC2a is that it's operating as a unity gain buffer, which is sort of the opamp equivalent of a cathode follower. Instead of providing voltage amplification the opamp is configured as a low impedance voltage source for the tuner output.
Of course, I could be totally wrong on this..."Stand back, I'm holding a calculator." - chinrest

Yes, good eye! You need a 1 meg to ground on the + input.Originally posted by Dave H View PostWARNING! Musical Instrument amplifiers contain lethal voltages and can retain them even when unplugged. Refer service to qualified personnel.

Thanks to all for your help, this scheme is a piece of Ampeg is a simple I'm looking for something more complicated, of course analog, something like Markbass. thing is that the solder will be my dad, I do not really judge of such works, know only as indicated by the details and what function held. sorry I do not know exactly the English language, I'm from Ukraine, but all grateful for the help!Comment
